October 2021: In this article, Martin Hartmann explains and demonstrates Aimsun Next microsimulation of vehicles equipped with cooperative adaptive cruise control (CACC).
How to generate throughput and demand outputs
September 2021: In traffic modelling, it can be useful to compare the traffic demand and the throughput along a route: how many people would like to make a journey and how many were able to carry out that journey within a set time frame.
Importing GTFS data into your Aimsun Next network
July 2021: GTFS feeds enable transit or public transport agencies to publish their data, and developers to write applications that use this data in an interoperable way. Dimitris Triantafyllos explores how to import this GTFS data into an Aimsun Next model.
